That was the message from hedge fund titan Ken Griffin Wednesday after hearing that 21st Century Fox (FOX) made an $80 billion bid for rival Time Warner (TWX).

"The deal makes a lot of sense," he said. "Let's get them to say yes."

Griffin has skin in the game on this one. Citadel, the multi-billion dollar investment firm that he runs, owns stakes in both companies.

Many analysts believe Rupert Murdoch will continue to aggressively push for the acquisition. So does Griffin. He believes that Time Warner makes sense as an addition to Murdoch's increasingly global media portfolio.

If Murdoch ups his offer, Griffin thinks it's "going to get tough" for Time Warner's board to say no again.

UBS said Tuesday that it lost $356 million on Facebook's IPO due to Nasdaq's trading glitches during the company's market debut in May -- and it plans to sue the stock exchange for every cent of it.

"UBS's loss resulted from NASDAQ's multiple failures to carry out its obligations, including both opening the Facebook (FB) stock for trading and not halting trading in the stock during the day," said UBS in MORE
